Buy to Let Mortgages

Whether you are a first-time landlord, an existing landlord or building a portfolio, Buy to Let lending depends on the property, expected rent, deposit, ownership structure and lender criteria.

What is a Buy to Let mortgage?

A Buy to Let mortgage is designed for a property intended to be let rather than used as your main home. Lenders often consider expected rental income alongside the applicant, property and mortgage details. Buy to Let borrowing is not a guarantee of rental profit or investment performance.

First-time landlords

Some lenders may consider a first-time landlord, although additional criteria and evidence can apply.

Existing and portfolio landlords

Existing mortgages, rental income and property values may be assessed together when you expand or refinance.

How much deposit might you need for Buy to Let?

There is no universal minimum deposit for a Buy to Let mortgage. The available LTV can depend on the lender, property type, landlord experience, rental coverage, applicant circumstances and whether you buy personally or through a company. Use our deposit calculator to estimate the funds needed, and our LTV calculator for an illustration of how LTV works.

Keep an allowance for valuation, legal work, tax, insurance, maintenance and periods without rent.

How does Buy to Let affordability work?

Buy to Let affordability can include expected rental income, personal income, existing commitments, property value and LTV. A lender may apply a rental stress test to check whether the anticipated rent covers its calculated mortgage interest at a stressed rate.

Interest Coverage Ratio

ICR is a calculation comparing rental income with mortgage interest under the lender’s assumptions. The required calculation is not universal and can vary by applicant and product.

Rental evidence

A valuer or lender may assess achievable rent, property type and local demand. An advertised rent is not the same as a confirmed lender assessment.

Personal Buy to Let or limited company?

A limited company Buy to Let mortgage may be available through an SPV or another company structure, but mortgage availability, rates, fees and criteria can differ from personal ownership. Personal guarantees may sometimes be required.

What is an SPV?

A Special Purpose Vehicle is a company created for a specific activity, which can include property investment. The lender will assess the company structure and directors.

Tax and legal consequences

Personal versus limited company ownership can have significant tax, legal and administration consequences. A limited company is not automatically more tax efficient; speak to a qualified tax advisor, accountant or solicitor before deciding.

Compare the ownership structure, lender criteria, rates, fees and tax and legal implications in our limited company Buy to Let guide before deciding.

Can you get a Buy to Let mortgage as a first-time landlord?

Some lenders may consider applicants without previous landlord experience, while others may have extra requirements. Your deposit, property, rental estimate, income and plans will all form part of the assessment. A first-time buy to let mortgage should be considered alongside the responsibilities and costs of being a landlord.

How are portfolio landlords assessed?

A landlord with multiple properties may be assessed across the portfolio rather than one property in isolation. Lenders may review existing mortgages, rental income, outstanding debt, portfolio LTV and rental coverage. Our portfolio landlord guide explains the factors to discuss before relying on a figure.

HMO, holiday let and other specialist lending

HMO mortgages

Houses in Multiple Occupation can need more specialist lending. Property configuration, licence requirements where applicable, landlord experience and rent assessment may be relevant.

Our HMO mortgage guide explains how property layout, licence status where applicable, expected rent and landlord experience can affect the discussion.

Holiday let mortgages

Holiday let or short-term letting is not necessarily treated like a standard assured-tenancy-style rental. Income assumptions, property use and lender criteria can differ.

Our holiday let mortgage guide explains why proposed use, income assumptions and lender criteria should be confirmed before relying on a rental estimate.

What does Buy to Let cost?

Consider the full cost of borrowing and running the property, including:

Rental income and property values can change. No Buy to Let mortgage guarantees a profit or return.

Are Buy to Let mortgages interest only?

Interest-only Buy to Let mortgages are common, but monthly payments do not reduce the capital. The full mortgage remains due at the end of the term, so an acceptable repayment strategy and a review of total interest cost are important.
